Patented May 22, 1906.

Application led June 29, 1905. Serial No. 267,501-

To all wtowt it may u/cern:

Be it known that I, GEORGE W. DY AR- MAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and usev ful Improvements in Concrete-Brick Machines; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accom- Io panying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The' invention relates to machines or apparatus for producing concrete bricks and the r 5 invention has particular reference to molds and pallets, whereby the bricks may be formed of plastic substance and supported until hardened suiiiciently to be handled independently of special holders.

zo Objects of the invention are to provide simple concrete-brick machines that may be cheaply constructed, capable of molding various styles of bricks, and be durable and economical in use, a further object being to pro- 2 5 vide machines that may be manually operated advantageously.

The invention consists in the improved and novel features of' construction in concretebrick machines and in the parts and combinations of parts, as hereinafter particularly described and claimed.

Referring to the drawings, Figure l is a top plan view of the machine arranged to form both rock-face bricks and bevel-edge bricks 3 5 at one operation; Fig. 2, a side elevation thereof; Fig. 3, a top plan of the combined mold-bottom and carrier; Fig. LI, a top plan of the mold-base and the partitions mounted thereon for forming the ends of the bricks;

inverted; Fig. 14, a perspective view of one Of the sections of the mold-front; Fig. 15, a

fragmentary top plan view of the machine modified so as to produce plain bricks and bricks with mitered corners; Fig. 16, an end view of the mold-bottom and the pallet to oo which the bricks have been transferred, the bottom being ready to be withdrawn; Fig. 17,

a fragmentary sectional view on the line C C in Fig. 2.

Similar reference characters in the different 6 5 figures of the drawings designate correspondinO elements or features.

In a practical embodiment of the invention a mold-base D is provided, which is in the form of a slab on the top of which a suitable 7o number of upright smooth metal plates are mounted that comprise partitions E for dividing the mold into sections and end plates E, E2, and *j* for shaping the bricks at the ends of the mold and at an opening intermediate of the ends thereof. The partitions and end plates are preferably composed of rolled steel and are secured to the base by means of angle-iron bars a and a, the end plate E being secured adjustably by means of angle- 8o iron bars c and c, having slots d therein and securing-screws e, the end plates E2 and E3 having a spacing-block b between them, a pair of the angle-bars securing all iixedly to the base D. The base D is stiifened 8 5 by means of a pair of longitudinal bars f and f', secured thereto against the under side thereof.

The combined mold-bottom and carrier comprises two longitudinal parallel bars F 9o and F, having handles g at their ends, and are each either formed of two parts or are rabbeted, and bottom plates G are secured to the bars so as to be flush with their top surfaces, the plates being separated so that openings h and 7L are provided to admit of the insertion of the partitions and the end plates above described. A filling-piece i, is attached by screws y' to one end of the moldbottom and carrier and may be removed when plain bricks are to be molded.

A mold-back II is formed of metal and has a smooth inner surface, the back being adapted to set upon the mold-bottom and carrier and is removable therefrom, and it has recesses 7c in its inner face to receive edges of the partitions and end plates, the ends of the mold-back having handles Z formed thereon.

IOO

The mold-fronts may vary somewhat for making different styles of bricks. The moldfront for molding ornamental bricks comprises a longitudinal bar I, having handles l on its ends and sits removably on the moldbottom and carrier opposite to the moldback. A suitable number f sections J and J and an end section J 2, which comprise pattern-plates, are secured detachably to the bar I, the sections J and J 2 forming rock-face bricks and the sections J forming bevel-edge bricks. If preferred, however, the bar may be provided with sections J in the places of the sections J, or sections J may be employed throughout the bar, in which case the end section J 3 should have a bevel-edge pattern, and it is to be understood that the section J 2 may have a bevel-edge pattern.

For making plain bricks a mold-front H is provided that has recesses 7c in its inner side to receive edges ofthe partitions and end plates and is somewhat similar to the moldback H, each having a recess m in its top to receive a clamp K, that is hinged to ears u and provided with a thumb-nut o, the bar I and mold-front H being provided with the ears u, so that the clamp may be changed from one to the other front. The clamp eX- tends between the plates E2 and E3 and holds the mold-back and the mold-front thereto.

The sections J and J have lips n projecting from their ends that bear against the ends of the partitions, as E, and the sections J2 and J3 have mitered ends p and p, respectively. The sections J and J have screwholes 1", that receive screw-bolts s for detachably holding the sections on the mold-front bars. The lips n serve as gages to make the bricks of proper width relatively to the plain bricks that may be made by means of the mold-front H.

A suitable number of pallets M are provided, each pallet having supports w, w, and x attached to the under side thereof, and when the pallet is set on edge on the mold-bottom against the bricks X and X it is broader than a brick, and the supports extend beyond the mold-bottom. The ends of each pallet have lugs y and y, that engage the bar F of the mold-bottom while the bricks are being transferred onto the pallet.

Tt is to be understood that the mold-front sections may be patterned in various styles, so that certain proportions of each style may be produced in the same mold at the same time and various patterns of corner forms, as N and N', Fig. 15, may be set into the molds to be removed from the bricks after they harden somewhat.

Clamps L and L are provided for the ends of the molds to hold the mold-back and the mold-front against the partitions and end plates, and, if preferred, a similar clamp may be removably applied in lieu of the hinged clamp K.

In practical use the base D is usually placed upon trestles or other support. Then the combined mold-bottom and carrier is to be placed upon the base, the partitions and end plates projecting through the apertures h and h. Then the mold-back and a moldfront are to be placed in position on the bottom and carrier and the end section J3 is to be placed against the end plate E. If plain bricks are to be molded, the filling-piece fi, is to be removed and the plate E should be moved into the place of the filling-piece, and the end section J 3 will not be required. The clamps should be applied, and then the concrete may be placed in the mold and tamped and then struck off, after which the clamps may be disconnected, the mold-back and the mold-front set aside, and the mold-bottom and' carrier lifted with the bricks thereon from the mold-bottom and carried to a suitable place, where a pallet should be placed, as in Fig. 9. Then the mold-bottom and pallet should be turned so as to place thepallet on the ground, as in Figs. l0 and 16, when the bar F will fall clear of the pallet-lugs and can be readily Withdrawn therefrom, leaving the bricks on the pallet to harden. Other operations will be obvious from the foregoing description.

Having thus is claimed as new is l. A concrete-brick machine including a base, a plurality of upright plates mounted upon the base, a slotted combined mold-bot tom and carrier, a mold-front and a moldback having each a recess in the top thereof opposite a space between two of the upright plates, and a clamp for the mold-front and the mold-back fitting in the slots and insertible between said two of the upright plates.

2. A concrete-brick machine including a base, a plurality of pairs of angle-irons attached to the base and each pair having an upright plate secured thereto, a pair of angleirons attached to the base and having a pair of upright plates secured thereto with a spacing-block between the plates, a slotted combined mold-bottom and carrier, a mold-front and mold-back, and a clamp for the moldfront and mold-back fitting between the two of the pair of upright plates.

3. A concreteebrick machine including a base, a plurality of pairs of angle-irons attached to the base, upright plates secured to the angle-irons, a pair of angleirons having slots therein and supporting an upright plate, screws attached to the base and eX- tending through the slots of the angle-irons described the invention, what IOO securing them adjustably to the base, a slotand carrier, a mold-front and a mold-back havingrecesses in the tops thereof adjacent to the ends of the upright plates, and a plurality of clamps for the mold-front and the moldback fitting in the said recesses.

5. A concrete-brick machine including a combined-bottom and carrier, arnold-back and a mold-front cooperating with the moldbottom and carrier and removable therefrom, partitions and end plates for forming the endso'l` the bricks, and a pallet having lugs for engagement with the mold-bottom and carrier for holding the pallet on the bottom and carrier against the bricks while'tilting the bricks from the bottom and carrier onto the pallet.

6. A concrete-brick machine including a combined mold-bottom and carrier, a moldback and a mold-front having each a recess in the top thereof, a hinged clamp 'fitting into said recesses and provided with a nut for clamping said back and front together, a base, and upright plates on the base.

7. A concrete-brick machine including a mold-back and a mold-front having each a plurality of recesses in the inner side thereof, a combined mold-bottom and carrier, clamps for the mold-back and mold-front, a base, and upright plates on the base YIitting into the recesses of the mold-back and moldfront.

8. A concrete-brick machine including a combined mold-bottom and carrier, a moldback having a recess in the top and a plural ity of recesses in the inner side thereof, a mold-front having patternplates thereon, a hinged clamp iittng into the recess in the top of the mold-'back and between two of the pattern-plates, a base, and upright plates on the base tting in the recesses in the inner side of the mold-back and also between the ends of the pattern-plates.
